Draft model 06 Magnetic Force & Hydraulic Force

Structure Change

Due to the use of the pipe structure, a variety of spring and rubber tests are required. If the weight of the water cannot press the pipe below the cover to help unlock it, the box will be locked forever.

Introduce magnetism

Considering the problem of saving space in the box, I want to develop a new unlocking method. Use other forces such as magnetism to alleviate the difficulty of unlocking with excessive water pressure. So I did this basic principle experiment. A round tube with a magnet at the bottom is used, and a hollow hemisphere is clamped in the middle. The hollow hemisphere is made of stainless steel (here, a magnet of the opposite sex is glued to the bottom instead). This can help the hemisphere sink with the help of magnetism when it reaches a little water directly. To achieve the purpose of unlocking.

After the experiment is completed, you only need to assemble a few thin wood boards plus this small structure to complete the box.
